Check the User guide for more information about writing Camel Quarkus applications.

Additional Camel Quarkus configuration

The extension automatically registers a Kubernetes Client bean named kubernetesClient. You can reference the bean in your routes like this:

from("direct:pods")
    .to("kubernetes-pods:///?kubernetesClient=#kubernetesClient&operation=listPods")

By default the client is configured from the local kubeconfig file. You can customize the client configuration via properties within application.properties:

quarkus.kubernetes-client.master-url=https://my.k8s.host
quarkus.kubernetes-client.namespace=my-namespace

The full set of configuration options are documented in the Quarkus Kubernetes Client guide.

Configuration property Type Default

quarkus.camel.cluster.kubernetes.enabled

Whether a Kubernetes Cluster Service should be automatically configured according to 'quarkus.camel.cluster.kubernetes.*' configurations.

boolean

false

quarkus.camel.cluster.kubernetes.id

The cluster service ID (defaults to null).

string

quarkus.camel.cluster.kubernetes.master-url

The URL of the Kubernetes master (read from Kubernetes client properties by default).

string

quarkus.camel.cluster.kubernetes.connection-timeout-millis

The connection timeout in milliseconds to use when making requests to the Kubernetes API server.

java.lang.Integer

quarkus.camel.cluster.kubernetes.namespace

The name of the Kubernetes namespace containing the pods and the configmap (autodetected by default).

string

quarkus.camel.cluster.kubernetes.pod-name

The name of the current pod (autodetected from container host name by default).

string

quarkus.camel.cluster.kubernetes.jitter-factor

The jitter factor to apply in order to prevent all pods to call Kubernetes APIs in the same instant (defaults to 1.2).

java.lang.Double

quarkus.camel.cluster.kubernetes.lease-duration-millis

The default duration of the lease for the current leader (defaults to 15000).

java.lang.Long

quarkus.camel.cluster.kubernetes.renew-deadline-millis

The deadline after which the leader must stop its services because it may have lost the leadership (defaults to 10000).

java.lang.Long

quarkus.camel.cluster.kubernetes.retry-period-millis

The time between two subsequent attempts to check and acquire the leadership. It is randomized using the jitter factor (defaults to 2000).

java.lang.Long

quarkus.camel.cluster.kubernetes.order

Service lookup order/priority (defaults to 2147482647).

java.lang.Integer

quarkus.camel.cluster.kubernetes.resource-name

The name of the lease resource used to do optimistic locking (defaults to 'leaders'). The resource name is used as prefix when the underlying Kubernetes resource can manage a single lock.

string

quarkus.camel.cluster.kubernetes.lease-resource-type

The lease resource type used in Kubernetes, either 'config-map' or 'lease' (defaults to 'lease').

org.apache.camel.component.kubernetes.cluster.LeaseResourceType

quarkus.camel.cluster.kubernetes.rebalancing

Whether the camel master namespace leaders should be distributed evenly across all the camel contexts in the cluster.

boolean

true

quarkus.camel.cluster.kubernetes.labels

The labels key/value used to identify the pods composing the cluster, defaults to empty map.

Map<String,String>

Configuration property fixed at build time. All other configuration properties are overridable at runtime.
